Development and Flood Risk

One in every five days during 2012 saw flooding in England and Wales


One in every five days during 2012 saw flooding in England and Wales, while one in four days were spent in drought.

There was flooding on 78 days of the year, and for 95 days there was official drought declared for some areas, figures from the Environment Agency show.

The extremes of weather that Britain has experienced over the past year highlight the urgent need to plan for a changing climate, the head of the Environment Agency (EA) has warned.

Rivers such as the Tyne, Ouse and Tone went from record low levels to experiencing their highest flows since records began, in the space of four months, the agency said.

Recent Met Office analysis suggests that the UK could experience a 1976-style drought every 10 years.

The EA said that with the population of London and the South East set to grow by 23% by 2035, action should be taken now.

Modelling suggests some river flows could be cut by up to 80% during the summer in the next 40 years as the climate changes, putting more pressure on businesses that rely on taking water from rivers for irrigation.

The EA has called for an increase in small-scale water storage reservoirs, which can take advantage of wet times and help farmers, commercial turf growers, golf clubs, sports stadiums and racecourses cope with dry periods.

There are currently around 1,700 such water storage reservoirs in England and Wales, supplying around 30% of irrigation needs, but they will need to increase as the UK faces more extreme weather as the climate changes, the agency said.

EA chairman Lord Smith said: “The extremes of weather that we saw last year highlight the urgent need to plan for a changing climate.

“In 2012 we saw environmental damage caused by rivers with significantly reduced flows, hosepipe bans affecting millions and farmers and businesses left unable to take water from rivers.

“But we also saw the wettest year on record in England, with around 8,000 homes flooded.
“Interestingly 2007 – which also saw some of the most severe flooding in recent memory – also started the year with hosepipe bans.

“More of this extreme weather will exacerbate many of problems that we already deal with including flooding and water scarcity, so taking action today to prepare and adapt homes, businesses, agricultural practices and infrastructure is vital.”

Garden Pond Design to Cure Existing Flooding Problem

A rather unusual but welcome commission this week, we usually design large attenuation ponds for SuDs schemes. This week, it’s a garden pond with an overflow within an exclusive housing development on the outskirts of Leeds to cure a flooding problem within the garden.

Yorkshire Practice Seminars – Flooding and Water, Managing the Risk

29th June 2011 at our offices at Grange Moor, only a few places left…

Following on from Planning Policy Statement 25 (PPS25): ‘Development and Flood Risk’ in December 2006, the Environment Agency (EA) has provided updated Flood Risk Standing Advice (FRSA). The updated advice reflects policy contained within PPS25 and the EA role as a statutory consultee on flood risk matters.  This seminar will bring this advice along with current practice up to the minute and add a planning policy perspective, a focus on Environmental Impact Assessment, the importance of FRA and environmental impact in the planning process and an engineering perspective, focusing on the Sanderson’s approach to these matters;

5.30 pm           Registration – Coffee and refreshments

5.45 pm           Chair’s Introduction – Bob Wolfe

New Website – added to our Expanding Portfolio

We are pleased to announce we have today launched a new website at

Flood Risk WebsiteThe new website is designed to target potential Clients who may require a flood risk assessment for small residential extensions to large employment, residential and office developments.

Sanderson Associates have vast experience in providing bespoke, site specific Flood Risk Assessments (FRA) and Flood Consequence Assessments (FCA) [Wales] for new developments and also existing facilities and we hope the content of our new sister website will assist Clients who require further information regarding Flood Risk Assessments (for proposed developments in England and Scotland), Flood Consequence Assessments (for proposed developments in Wales), Flood Modelling, Breach Analysis and Flood Risk Business Continuity Services.
